Full title and description

ISO 12319:2006 — Aerospace — 'P' (loop style) clamps — Procurement specification. This International Standard defines procurement and quality-assurance requirements for 'P' (loop style) clamps used in the installation of aerospace fluid systems, with a focus on ensuring consistent performance and safety for clamps used in flight-critical and fluid-handling applications.

Abstract

Specifies the contractual, material, dimensional, testing, inspection, marking and certification requirements for loop-style ('P' form) clamps used in aerospace fluid systems. The standard covers qualification and requalification procedures, performance tests (including retention, vibration, ozone and titanium-compatibility checks where applicable), workmanship and acceptable sampling/inspection plans to ensure supplied clamps match qualified performance.

Scope

Applies to procurement of loop-style (P‑form) clamps intended for installation in aerospace fluid systems. The scope includes requirements for materials and configuration, dimensional tolerances, surface treatment and workmanship, identification and marking, qualification and periodic requalification, specified performance tests (retention, vibration, ozone and titanium compatibility where relevant), inspection/sampling procedures and required documentation and certification to be supplied with lots or qualification deliveries.

Key topics and requirements

• Procurement specification and contractual requirements for clamp supply and acceptance.
• Material, configuration and dimensional requirements for 'P' (loop-style) clamps.
• Workmanship, surface treatment, marking and traceability requirements.
• Qualification, product approval and periodic requalification sampling rules.
• Performance testing: retention (axial retention force), vibration, ozone resistance for elastomer cushions, titanium-compatibility tests, and optional UV or electrical insulation tests when required.
• Inspection and sampling procedures (sampling plans consistent with ISO sampling practices) and documentation/certification to accompany deliveries.

Typical use and users

Used by aerospace OEMs, subcontract manufacturers and suppliers of fluid-system hardware, procurement and quality assurance engineers, design and installation engineers for aircraft fluid systems, maintenance/repair organizations, and certification or approval authorities verifying that supplied clamps match qualified performance characteristics.

Related standards

Standards commonly referenced together with ISO 12319:2006 include sampling and inspection standards (e.g., ISO sampling practices), elastomer and environmental test standards (for ozone and UV resistance), and specific aerospace fluid-system standards produced by ISO/TC 20/SC 10. Specific related test standards often applied in conjunction include those for ozone resistance, vibration testing and electrical insulation where applicable.

FAQ

Q: What is this standard?

A: ISO 12319:2006 is an ISO international standard that provides procurement and quality-assurance requirements for 'P' (loop style) clamps used in aerospace fluid systems.

Q: What does it cover?

A: It covers material and configuration requirements, dimensional and surface criteria, testing (retention, vibration, ozone, titanium compatibility and optional tests), inspection and sampling, marking, documentation and procedures for qualification and requalification of loop-style clamps.

Q: Who typically uses it?

A: Aerospace OEMs and tiered suppliers of fluid-system hardware, procurement and QA engineers, installation and design engineers, maintenance/repair organizations, and authorities responsible for product approval and certification.

Q: Is it current or superseded?

A: As published, ISO 12319:2006 is a published International Standard (edition 1, 2006). It has been subject to periodic review by ISO and remains the 2006 edition; users should check their national standards body or ISO for any confirmation of current status or later revisions before assuming it is unchanged.

Q: Is it part of a series?

A: It is a stand‑alone procurement specification focused on 'P' loop‑style clamps and was prepared within the work of ISO/TC 20/SC 10 (aerospace fluid systems and components). While not formally a numbered multi‑part series, it is often used alongside other ISO standards for testing and sampling.
